Seaweed nursery

Seaweed is a greatly underestimated resource that provides food and shelter to marine life. It is also used as a food source for people - often referred to as a 'superfood' that is rich in iodine and calcium and contains natural antioxidants, minerals and amino acids. Seaweed is also an important source for future supply of food and feed (additives), pharmaceuticals, cosmetics, biomaterials and bioenergy.

Seaweed farming is a mature multi-billion dollar industry and some Asian countries produce tens of millions of tonnes a year. But although seaweed grows prolifically in Scottish waters, seaweed farming in the UK is is only in the early stages as an emerging industry.

SAMS is conducting research that would support an industry to develop, much of it using its experimental seaweed farms. These facilities support research projects such as Seagas, Macrofuels and Genialg.

The SAMS seaweed nursery is a facility dedicated to the out-planting and cultivation of seaweed strains for research projects and commercial supply.

Cultures include the seaweed strains Saccharina latissima, Alaria esculenta, Laminaria hyperborea and Laminaria digitata.

Nursery time is approximately 5-8 weeks, depending on the species and methods used.

Our nursery facilities include:

  • >Incubators
  • >Microscopes
  • >Autoclave
  • >Laminar flow cabinet
  • >LED lighting
  • >Temperature control
  • >Filtered and UV treated seawater supply

Through this facility, SAMS has the capacity to produce 6km of seeding twine with plans to expand this to over 25km in the next years.

At present the nursery is undergoing a biosecurity upgrade to allow the cultivation of non-local varieties.
